Original No. 1,354,846, dated October 5, 1920, Serial No. 374,519, filedApril 17, 1920. Application for reissue filed February 10, 1921.

To all whom it may concern:

Be it known that I, JAMEs ROBERTSON, Jr., a citizen of the United Statesof America, residing at Weehawken, county of Hudson, and State of NewJersey, have invented new and useful Improvements in Repair- Patches forRubber Footwear, of which the following is a specification.

This invention relates particularly to a repair patch applicable to thetoe or heel of a rubber or overshoe, and the object is to provide apatch of such form that it may be applied to either the toe or heel, andto a considerable range of models and sizes so that the repair man isunder the necessity of having in hand only a limited number of differentsizes of repair patches in order to be repared to repair any size ormodel of rub er or overshoe that may be offered. A further object is toprovide a form of repair patch that may be applied expeditiously and ina substantial and workmanlike manner.

In the accompanying sheet of drawings which forms a part of thisapplication Figure 1 is a top view of a repair patch according to thisinvention.

Fig. 2 is a side view of the same.

Fig. 3 is a section on the line III-III of F i 1 and 2.

Fig. 4 shows a patch applied to both the heel and toe of a rubber, thepatch being in section on the line IV--IV of Figs. 1 and 3.

The repair patch is preferably a single molded piece of rubber andcomprises a heavy tread portion 5 with a thickness, for example, of froman eighth to three-sixteenths of an inch so as to stand considerablewear. This thickness is such that it is comparatively inelastic. Thisportion is rounded at one end and is of suflicient area to cover all ofthe heel or as much of the sole as it is desired to cover. Upstandingfrom the rounded end of the tread portion is a flange 6 which curvesover the tread portion. The fian e at the bottom margins 7, 7 of itsends is s arply incurved and joins to the tread portion at a distancefrom the margin of the tread portion. In consequence of the manner ofjoining the repair patch can be fitted to a. rubber or overshoe whichhas a heel or toe with a width equal to the distance between the pointsof joining of the incurved margins with the tread portion, or

which has a greater width, and the flangev can be bent'into contact withthe sides of the Serial No. 444,054.

rubber when it is narrow, or, when the heel or sole 1s wide the incurvedbottom margin may be rolled out to accommodate the greater wldth. Whenapplied at the heel the upper edge of the flange will be some whatstretched and the flange bent back. When applled at the toe the flangemay need to be curved somewhat more than its normal form.

By reason of the flange being curved over the tread portion and alsobeing thin, flexible and elastic it can be turned inside out and rolledunder the tread, and when this is done 1t will not spring back of itsown aocogd.

n preparation for ap l in the flan e is first turned under the t i'eiidand cemei it is applied to all of the surfaces of the repair patch andof the rubber or overshoe which are to come together and-the cementallowed to dry. lhe tread is then applied to the heel or sole with theflange still rolled back and after ap lying the flange is rolled up intoplace. fter applying any portions of the tread whlch project beyond theheel or sole are trimmed off.

1 find that because the material of the flange is thin, flexible andelastic, the incurve at the bottom margins 7, 7, though desirable, isnot essential. Therefore I do not wish to hunt myself by the inclusionof this feature in the broader claims.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. A repair patch for footwear comprising a tread portion rounded at oneend and having a flexible and elastic flange upstanding from the roundedend of the tread portion and having the bottom margins at its ends oinedto the tread portion at a distance from the margin of the tread portionand sufiiciently t in and flexible to have a bending line at itsjuncture with the tread portion whereby the flange can be brought intocontact with the sides of the footwear when it is narrow and may bebrought into contact, with the projecting margins of the tread portionto accommodate wider footwear, substantially as described.

2. A repair patch for footwear comprising a tread portion rounded at oneend and having a flexible and elastic flange upstanding from the roundedend of the tread portion and having the bottom margins at its endsincurved and joined to the tread portion at a distance from the marginof the tread portion, substantially as described.

3. A repair patch for footwear comprising a tread portion rounded at oneend and 5 having a flexible and elastic flange upstanding from therounded end of the tread portion and curved over the tread portion andhavin the bottom margins at its ends incurve and joined to the treadportion at a distance from the margin of the tread por- 10 tion,substantially as described.
